    <p>
    With this command it is possible to use an external program 
    as a Scilab command
    where  <tt>
        <b>(s_1,s_2,...,s_lhs)</b>
      </tt> are the output variables and
     <tt>
        <b>(e_1,e_2,...,e_rhs)</b>
      </tt> are the input variables. To insert this command 
    in Scilab one has to write a few lines in the <tt>
        <b>user</b>
      </tt> fortran subroutine
    of Scilab. See <tt>
        <b>intersci</b>
      </tt> or the Scilab documentation for more information.</p>
